Support for Arduino auto-reset:

Browse Source 
* serial.h, ser_avrdoper.c, ser_posix.c, ser_win32.c: Added 
	  serial_device.set_dtr_rts implementations.
	* arduino.c, stk500.c, stk500.h: Call serial_set_dtr_rts()
	  to reset Arduino board before program upload.
	Inspired by patch #6866, resolves bug #26703
